PI2DDR321 (Obsolete)

Description

PI2DDR321 is a 1 bit 2 to 1 GDDR5 mux operating at 1.35V/1.5V supply and is designed for GDDR5 memory bus with speeds up to 5 Gbps. It is used to gate the clock signal only when bus is active thus saving power. 

Feature(s)

• 1-bit 2:1 switch that supports up to 5Gbps GDDR5 signals
• VDD 1.35V/1.5V +/- 5%
• SEL and Global Enable
• 170 μA typ. operating current
• High impedance and low Coff channel output when disabled or deselected
• Low RON: 8Ω typical @ VIN = 0V & IIN = 40mA
• 3dB Bandwidth: 3.3GHz
• Low insertion loss: -0.6dB (0≤f≤1GHz)
• ESD: 2KV HBM

Application(s)

• GDDR5 power management in GPU applications in notebooks
